修改使用者設定檔userChrome.css， 增加如下內容：

/* Make menus XP style */

menupopup, popup {
    border: 1px solid ThreeDShadow !important;
    -moz-border-left-colors: ThreeDShadow !important;
    -moz-border-top-colors: ThreeDShadow !important;
    -moz-border-right-colors: ThreeDShadow !important;
    -moz-border-bottom-colors: ThreeDShadow !important;
    padding: 2px !important;
    background-color: Menu !important;
}

menubar > menu {
    border: 1px solid transparent !important;
    padding: 2px 5px 2px 7px !important;
    margin: 0 !important;
}

menubar > menu[_moz-menuactive="true"] {
